Next-level thermal performance in the Mythic Ultra Jacket for severe alpine cold
What Our Gearhead® Experts Are Saying:
"I reach for this when I know the cold will hit hard and linger. The down lofts fast, the TILT lining genuinely boosts warmth on static belays, and the whole jacket still feels lighter than seems possible. It’s become my go-to for freezing conditions where every gram and every degree of heat matters."
We know the difference a truly warm layer can make on a bitter alpine morning, and the Mythic Ultra Jacket from Rab gives us confidence the moment temperatures take a hard dive. The combination of 900-fill hydrophobic down and Rab’s TILT reflective lining creates an insulating system that feels powerful without feeling heavy, letting us stay focused on the pitch instead of the cold settling into our core. Whether we’re gearing up for a long ice belay or moving between cruxes on winter rock, the warmth-to-weight ratio keeps this jacket permanently in our pack.
Rab’s Pertex Quantum shell blocks sharp winds without slowing us down, and the helmet-compatible hood adjusts cleanly for secure coverage when the air turns sharp. As we transition, the jacket compresses neatly into its stuff sack, storage that makes sense on missions where space is tight and every item must justify its place. With durable ripstop fabric and a thoughtful pocket layout, it’s built for real mountain travel, not just mild weather days.
